Algorithmic complexity of proper labeling problems
Ali Dehghan, Mohammad-Reza Sadeghi, Arash Ahadi
A proper labeling of a graph is an assignment of integers to some elements of a graph, which may be the vertices, the edges, or both of them, such that we obtain a proper vertex co…

On the Lucky labeling of Graphs
Arash Ahadi, Ali Dehghan, Esmael Mollaahmadi
Suppose the vertices of a graph were labeled arbitrarily by positive integers, and let denote the sum of labels over all neighbors of vertex . A labeling is lucky i…
